Patent number: 10455061Abstract: A smart NIC (Network Interface Card) is provided with features to enable the smart NIC to operate as an in-line NIC between a host's NIC and a network. The smart NIC provides pass-through transmission of network flows for the host. Packets sent to and from the host pass through the smart NIC. As a pass-through point, the smart NIC is able to accelerate the performance of the pass-through network flows by analyzing packets, inserting packets, dropping packets, inserting or recognizing congestion information, and so forth. In addition, the smart NIC provides a lightweight transport protocol (LTP) module that enables it to establish connections with other smart NICs. The LTP connections allow the smart NICs to exchange data without passing network traffic through their respective hosts.Type: GrantFiled: December 20, 2017Date of Patent: October 22, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Adrian Caulfield, Eric Chung, Doug Burger, Derek Chiou

Patent number: 8868867Abstract: Systems and methods of storage device access are provided, where the operating system copies permission and mapping information to the storage array and/or to the application program's memory. The application program can then access the storage device without the operating system's intervention and the storage device will check whether the application has permission to access the data. As a result, in most cases, neither the operating system nor the file system needs to be invoked, and since both of them increase the amount of time required to access the data in the file system, considerable performance improvements are possible.Type: GrantFiled: September 14, 2012Date of Patent: October 21, 2014Assignee: The Regents of the University of CaliforniaInventors: Steven Swanson, Adrian Caulfield, Todor Mollov
